My composition consists of a mixture of natural orange shellac, Venetian turpentine,

colophony and mastic.

' Also the transparent sealing composition can be thinly spread over a surface upon which has been written the signature of the dispatcher of the message and due to its transparent nature, the signature can be seen .therethrough very clearly. An attempt therefore to remove the seal wou d remove the signature as well, due to the great afiinity of t e sealing wax to the paper. In this wa a perfect seal is provided for letters an the like.
